yTo all whom it may concern:

Be it known that I, JAMES A. SHARP, a citizen of the United States, residing at Springfield, in the county` of Clark and State of Ohio, have invented certain new and useful Improvements in Billing-Presses, of which the following is a full, clear, and exact specification.

This invention relates to baling presses, and more particularly to block case operating mechanisms therefor.

One of the objects of this invention is to simplify and improve theblock case operatv ing mechanism.

Another object of the invention is to simplify and improve the control of the block case operating mechanism.

Anotherl ob]ect is to provide a baling press having block case operating mechanism adapted to meet all the requirements for successful commercial operation.

These and other objects are accomplished by providing in a baling press a block case, improved operating mechanism for actuating the same, and improved control means associated with the block case and actuating means.

The invention is illustrated on the accompanying sheets of drawings, in which- Figure 1 is a fragmentary side elevation sition after having released the block from the casing to permit the same to fall into the compressionchamber, the other parts being in corresponding positions;

Fig. 2 is a fragmentary side elevation of the same vhay press with the feeder head in its raised position and the other parts in their corresponding positions;

Fig. 3 is a fragmentaryelevation of the feeder head and operating parts associated therewith as viewed from the right in Fia '2;

The various novel features of my invention will be apparent from the following description and drawings and will be particularly set forth in the appended claims.

The hay press 10 here shown, in general, includes the frame structure forming a compression chamber 11 and a baling chamber 12, there being.` a compression plunger 13 connection from the compression plunger in-v cluding a link 1G, arm 17, shaft 18, on which is mounted an arm 19, connected to a link 20, a suitably supported bell crank 21, a link 22 between the bell crank 21 and an arm 23 mounted upon one end of a rock shaft 2-1, upon which is secured a casting 25 connected to the main arm 26 of the feeder head 15. Thisifeeder head is pivoted intermediate its ends to one end of the arm 26, and in order to'prevent injury to the feeder head or cooperating parts if the feeder head should strike an unyielding obstruction, the arm 26 and the casting 25 are yieldably connected together by the usual spring and bolt. arrangement 28 associated with such parts.

' Secured to the main frame of the press on opposite sides thereof are two vertically arranged supporting members 29 and 30, the upper ends of which are bent over and secured to the upper bent portions of two other supporting members 31 and 32, which also are secured to the main frame of the press. The supporting members 29 and 30 are connected by a cross bar 33, and the frame inembers 31 and 32 are connected by a similar cross portions of these guide rods arc secured by suitable clips 37 and 38 to a block case 39 for the reception of a block 40, which is yieldingly retained therein by spring-pressed straps 41 of the block case, which straps terminate in offset tip portions 42 engaging a lower edge of the block 40. Theblock 40 is normally supported on a suitable table 43, from which the casing and block are pushed laterally when the block case operating" mechanism is thrown into gear. Secured to i and connecting the guide rods 35 and 36 is an adjustable bracket 44 having a passageway 45 extending therethrough, and in this passageway there being located a shoulder 46 which is adapted to be engaged by one end of a push rod 47 ,the other end of which is pivoted to one end of a rocker arm 48 pivoted in a bracket 49 secured to the cross bar 33. The other end of the rocker arm 48 is provided with a roller 50, which under certain conditions is held in Contact with a hook-shaped cam 51 connected to the feeder y head arm 26 and receiving its motion from the rock shaft 24. A spring 52 connects the upper part of the rocker arm 48 to the block case in a manner such that the spring tends to hold the block case on the table 43 or to pull. it back onto such table when removed therefrom, the spring 52 also tending to hold 57 and 58, respectively, the first projection CaSe.

57 when in one positioinas shown in dotted lines 1n Fig. 2, engaging a shoulder portioil 59 of the push rod 47 to hold the push rod up out of engagement with the shoulder 46 of the bracket`44. In other words, the projections 57 in the position shown in dotted lines in Fig. 2, holds the block case operating mechanism out of lgearfwith the-blocl However, when the control lever 53 is Athrown forwardly from the position shown in Fig. 2 tothe position shown in Fig. 1, the projection 57 is lowered to permit the push rod 47 to fall into a position on a level with the shoulder 46; or, in other words, to permit the block case operating mechanism to be thrown into gear. When the control member 53 is thrown forwardly into operative position, the other projection 58 (see Fig. 6) is thrown under a hook portion 60 of a -leaf spring 61 secured to the bracket 44,

.v gear. necessary to throw the lever 53 forwardly whereby the control lever is yieldingly retained in such position and the latch 57 isA yieldingly locked against throwing the push rod 47 out of engagement with the shoulder 46; or, in other words, to prevent the proj ection 57 from throwing thevblock case operating mechanism out of gear. The spring 61 also servesanother function, and that is to kautomatically throw the block case operatcase with a reasonable degree of accuracy;

that is to say, the block must be placed substantially in the center of the case. The block may be inserted from either side by depressing one or the other of two weighted members 62, pivotally connected to the side frame members 31 and 32, and sliding the block until it strikes the other of said members. The block may then be locked in the case against lateral movement by the horizontally arranged portions of the weighted member 62. If the weighted portion of one of the members 62 is lifted, it may act as signal that the block is not properly placed wholly within the case. A careless operator may not place the block wholly within the case and may not pay any attention to the position of the weighted member 62. However, if the block extends laterally out of the case, it will be impossible to throw the operating mechanism into gear because of the fact that one or the other of two longitudinally eX- tending spaced rods 63 connected to the arms 54 of the control lever 53 will pass into engagement with the block, as shown in Fig. 4. Therefore, in order to throw the operating mechanism into gear, it is necessary that theblock be properly placed in the case. In this manner no injury can be done to the machine by improper placing of the .block within the case.

Normally the block case operating mechanism is outof gear for about twelve to fifteen cycles of the feeder head. As shown in Fig. 2, the operating mechanism. is out of To throw it into gear, it is merely or toward the block case. If the block is properly set in the case, the rods 63 will pass on opposite sides of the bloc-lr to permit 'the actuating means and associated parts to `be thrown into gear, and, as above stated, 1f the block is not centrally set, one of these Vlinks will pass into engagement with the block to prevent the case operating mechalis ' f a'erating mechanism is automatically thrown @out of gear. l/Vith the case operating meehanisin out of gear, the feeder head 15 continues 1 as shown in Fig.2, the projection 57 permits der `4b on the guide rod bracket 44,v and the H tion 58m a manner to automatically lift the other projection 58 passes underk the leafspring 61 to yieldingly hold the lever 53 in' its operative position. At the same time the spring 52 will draw the roller 50 into contact withthe cam 5l and will draw the push rod 47zinto a position to positively insure its `passage into engagement with ,the shoulder 46. Now, if the feederliead 15 is lowered, y Y the cam 51y will rock the rocker arm-48-` to actuate the push rod 47 which is effective in pushing the case and 'block away from the table-13 and into a position where an arm 64 on vthe `feeder head may force the block out of the case. As the case is moved away from `the table 43, the case returning spring 52 is placed under added tension. i This spring 52 j returns the case toward its normal position as the cam 51 permits same. Just as the cam 5l passes away from the roller, as shown particularly in Fig. 7, the leaf spring 61 on the guide rod bracket 44 pushes the projecprojection 57 to raise the push rod 47 out of 'engagement with the shoulder 46 and to `push Vthe control lever 53 to its initial inoperativeposition; that is tosay, the case opas usual onits next down feeding stroke, and

of course, the cam 51 actuates 'the push rod j forward again, but, being out of gear, the

j .rod-doesnot actuate the case. It merely `lslides through the passageway 45 kabove the bracket shoulder 46. This time on its forward stroke the push rod 47 also rides .over

' that asthe feeder head now rises, the roller 50 will not follow'the cam 51, even under "the tension of the spring 52; that is to say, the push rod 47 is hooked up. VUnder these conditions, during the next twelve or fifteen strokes, while the block case is at rest, there @operating mechanism into gear. As soon as will bc no wear between the'cam and roller.

`The case will not be actuated again until the lever-53 is thrown manually to place thecase the lever 53 is thrown forwardly, the spring,

which is under tension, will again throw the roller into contact with the cam, and if the i feeder head is raised, will throw the push y'rod 47 into operative engagement with the `shoulder on the guide rod bracket 44 for ,actuating the case on the next 'downward movement of the feeder head 15. l
